a powerful network data visualization technique that facilitates the detection of emerging trends & transient patterns in scientific literature. CiteSpace is based on 2 concepts: "research fronts", defined as an emergent grouping of concepts & underlying research issues & "intellectual base", the network of citations & co-citations of a research front in scientific literature. the size of a node is proportional to the normalized citation counts in the latest time interval.
the label size of each node is proportional to citations of the article, thus larger nodes also have larger-sized labels. the user can enlarge font sizes at will, & both the width & the length of a link are proportional to the corresponding cocitation coefficient. the color of a link indicates the earliest appearance time of the link with reference to chosen thresholds. current applications show complex patterns regarding mass extinction research & terrorism research.
